* ''Date: [[1554]]''
* ''Japanese'': 甲相駿三国同盟 ''(Kousousun Sangoku Doumei)'' or 善徳寺の会盟 ''([[Zentoku-ji]] no Kaimei)''


In the mid-1550s, the [[Imagawa clan|Imagawa]], [[Go-Hojo clan|Hojo]], and [[Takeda clan|Takeda clans]] met at the Zentoku-ji temple in [[Suruga province]] and established a peace treaty.  The proceedings were moderated by a monk named [[Taigen Sessai]].  The three daimyo agreed not to attack each other, as well as made agreements on support and reinforcements if necessary. This agreement was held together by three marriages - [[Hojo Ujimasa]] married the daughter of [[Takeda Shingen]] ([[Obai-in]]), [[Imagawa Ujizane]] married a daughter of [[Hojo Ujiyasu]], and [[Takeda Yoshinobu]] had already married the daughter of Imagawa Yoshimoto in 1552, further strengthening ties between the Takeda and the Imagawa. Due to these agreements, the three daimyo were able to focus on thier own goals without fear of attack.

This peace treaty layed the foundation for Imagawa Yoshimoto to focus on the [[Oda clan]] in [[Owari province|Owari]], and attempt a move on Kyoto<ref>If Imagawa Yoshimoto had not made peace with the Hojo and Takeda, he may not have invaded Owari in 1560 to be killed by Oda Nobunaga. Had that not happened, the entire history of the Sengoku may have changed completely.</ref> The Hojo clan benefitted by being freed up to expand thier own influence in the Kanto, and Takeda Shingen was able to focus on his invasion of [[Shinano province]].

The Japanese name of the alliance, 甲相駿三国同盟, literally means "Alliance of the three provinces of Kai (Takeda), Sagami (Hôjô), and Suruga (Imagawa)."
